method and device treats cancer where blood from a cancer patient passes through an array of passageways within an interior of a chamber. The passageways include wells having porous membrane wall portions that enable a molecular-sized activating agent in a carrier fluid that enhances an immune response to pass through these porous wall portions. Pore size is such to allow the molecular-sized activating agent in the interior of the chamber to enter the wells yet prevents immune cells and cancer cells in the wells to pass through the porous wall portions into the interior of the chamber. Blood is retained in the wells so that it remains in contact with the immune cells and cancer cells for a predetermined period sufficient to enhance an immune response. Then the cells with an enhanced immune response are return to the patient.

Extracorporeal blood treatment is performed daily on a large number of patients by use of for example a dialysis filter, plasma filter or a centrifuge. The purpose of the treatment is to separate minor components and molecules in a liquid or in the blood from larger ones, for example in connection with different disease conditions or with a view to extracting blood plasma, target substances such as blood components or molecules from for example blood donors. According to the present invention two separation steps are used together with a solution or a suspension containing at least one component, which specifically may bind to the component or the blood component to be specifically reduced, or to be refined/extracted during the treatment or during the blood treatment.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium an energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The energy modulation agent has a normal predominant emission of radiation in a first wavelength range outside of a second wavelength range (WR2) known to produce the change, but under exposure to the applied initiation energy produces the change. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.
